Armature bracket

For the installation of water piping in walls one has in later years started to use plastic pipes or sturdy plastic hoses, that are placed in a surrounding thin walled and corrugated hose. If the thick walled inner hose should start to leak the water is drained away in the surrounding hose to a central or branching point, preventing water damages to the building and furthermore indicating which hose that is damaged. The inner sturdy hose or flexible piping can furthermore when damaged be exchanged far easier than for instance integrated copper tubing where one have to brake up the wall or parts thereof. The technique is called pipe in pipe or PIP and reduce the installation costs considerably as compared to the use of copper pipes.

One is however at many connections for outlets and shower and bath tub mixers still forced to break up the wall. If the wall is thin the bending of the pipes, for which a surrounding fixture is used will be so sharp that the inner pipe will be locked and one can not in reality withdraw the old one and insert a new one. The breaking away of tiles and other wall covering as well as gypsum etc below thus constitutes a considerable drawback for the PIP-technique. The opening up of bathroom walls and restoration is not only costly but also disturbing since it takes time, in particular since several different categories of professionals have to be summoned. The object of the invention is to eliminate the above problem efficiently. The problem is in accordance with the invention solved by the arranging of a panel or mounting bracket that is angled in relation to the wall, preferably 45°, and that a complementary angled pipe coupling is arranged at the outlet side so that a connector for instance for a shower armature will be angled perpendicularly to the wall. Since the pipe/hose at the passage out through the wall is inclined the tension forces at the bend will be moderate even at a thin wall and no further special fixture is needed, the pipe will be free from tensions which ensures good exchange possibilities, as well as a smaller risk of damages at mounting as well as at demounting and also in place and at use.

By using a bracket that is inclined 45° and an outer connection of a completing 135° it will also be possible to turn the connection so that it becomes vertical, which for instance may be advantageous at the connecting of shower cabinets where the connection is situated

between the wall of the shower cabinet and the wall of the room.

Advantageously the mounting bracket has the shape of a rooflike part that is provided with passages for the pipes placed on the same roof side, if there are several connections, which roof is surrounded by a flange constituting a plane going all around for fastening to the wall. The wall bracket may of course include more than two connections that may be arranged on different sides of the "roof", for instance for the connection of several shower cabinets, likewise one can consider brackets only being provided with one connection.

The mounting bracket may either be applied with the roof part protruding out from the wall or recessed into the wall and may further be placed horizontally or vertically. The triangular shape provide great strength and stability and since the fastening to the wall is a distance from the connection itself the risk of tensions in the hoses or forces on mounted armature causing the fastening to become loose is reduced.

Advantageously furthermore a shut off valve may be integrated in the angled connection part for use at an exchange of shower mixer or seals therein. Since the connection parts are angled the shut off valve can be integrated in the bend itself without the connection parts having to be made larger, that is in- and outlet do not need to be longer from each other than at a connection bend without integrated valve. The installation in accordance with the invention will thus be very close to the wall, in particular if the bracket is recessed into the wall. The available space in for instance a shower can thus be utilized better. The wall bracket may further be used for the mounting of, or fastening of, for instance a basket or shelf for shampoo, brushes and sponges etc.

It is easy to pull out the inner hose and insert a new one.

The invention is below to be described by way of an embodiment of the invention with reference to enclosed drawings. In these fig 1 shows the device according to the invention seen in a section in the length direction of the pipe, fig 2 the connection in an exploded view, partly in cross section, and figs 3 and 4 respectively a wall bracket with the connection facing upward and horizontally respectively.

In fig 1, in full scale, an outer flexible pipe 1 is shown in a wall 3, inside this flexible pipe an inner thick walled, stiffer but flexible pipe 2 is arranged and on the inner side 4 of the wall a wall bracket 5 is fastened in the wall by means of screws 6. The outer pipe ends at the profile while the inner pipe 2 extends out of outer pipe and bracket and into the room

through a riveted turnably fastened coupling nut 11. The inner pipe is cut a distance outside the nut 11 and a counter-tube 12 is inserted into the pipe 2 and a conical part 13 is pushed on the inner pipe (fig 2). The nut 11 is then threaded on a thread 14 on the inlet side of a valve housing 7 so that the plastic pipe is clamped between the cone 13 and the counter-tube 12.

The surface or the part 10 on which the passage holes of the bracket are arranged is inclined 45° in relation to the wall plane so that the bend for the flexible pipes or hoses 1 , 2 in the wall become gentle and manageable with a large bending radius. This in spite of the fact that the wall is thin with only 70 mm studs. A further advantage with the invention is that the flow of the water will be straighter with less sound and pressure drop as a result. Due to the level path of the inner pipe this can easily be drawn out and pushed in again at repair and alterations.

The connection 8 fastened to the wall bracket in fig 1 for instance for a shower mixer include the above valve housing 7 that has an angle of 135° between inlet and outlet and a valve ball 9 with teflon seal. The valve ball 9 is arranged in the bend of the valve housing 7.

In fig 3 the connection 8 is turned upwards for a vertical connection and in fig 4 the connection 8 is turned so that the outlet is horizontal.

The wall bracket has the shape of a roof with two roof surfaces and gables and a surrounding flat brim or flange that is used for the fastening to the wall.

The bracket has on its bottom side close to or in the transition from roof surface to flange a hole 15 for the draining of water that comes out from the corrugated pipe in its upper end if the inner pipe should start to leak. The corrugated outer pipe is sealed relative the wall and the sealing membrane applied on this and there is thus no risk that water penetrate into the wall.

If so desired one may within the frame of the invention consider the draining of the water from the outer piping being arranged at the coupling nut 11 that is fastened to the bracket.
